Abstract
The compressive sampling spectral modulated technique is developed in order to avoid time penalty and promote throughput of spectral imaging system,and a digital-micromirror-device based compressive sampling multispectral imaging system is designed.In the technique based compressive sampling spectral information is sampled below Nyquist-criterion with coded aperture to reduce spectral data greatly.In the experiment,the cubic spatial/spectral data cubes of the 612 nm laser and colored striped fabric are reconstructed from 2-Dimension images obtained from detector that contain spectral information using double shrinkage fast iterative algorithm.The results indicate that a digital-micromirror-device based compressive sampling multispectral imaging system has images with high-throughput and high resolution,can compress the spectral simultaneously,and the compression ratio can reach 31∶1.
